Vsauce Asks, ‘How Many Calories are on a Smudgy Screen?’ In Latest Viral Video

We’ve already learned from Vsauce why you can’t see the color yellow on your computer screen and how 1 billion people jumping at once wouldn’t make a difference in the Earth’s rotation.

Now in his latest viral YouTube video from his parents’ basement back in the United States, London-based YouTube pop science vlogger Michael Stevens talks about our fingerprints and how each of us has a unique design starting from birth. Even identical twins will have a different set of fingerprints.

Besides getting into the intricate details of fingerprint development, Stevens also explains what constitutes those fingerprint smudges on your smartphone or any other seemingly clean surface you touch.

When NMR talked to Stevens back in September after his channel reached the 1 million subscriber mark, he credited Vsauce’s success to “simply showing that a silly or mundane topic can quickly become mind-blowing if you look closer, read a lot, and let your curiosity go crazy.”
